A data link functions as an M/M/1 queue. Packets arrive at a rate 5104 per second, and are served at a rate 105 per second. How large must the buffer be that the probability of buffer overflow be less than 109? What is the average number of packets in the queue? How long does each packet stay in the queue on the average?
